Hotaru Akane, also known as Anna Akizuki and Hotaru was a Japanese actress, HIV/AIDS activist, and AV idol. She was active in many media formats in Japan including mainstream theatrical film, and was a popular blogger. Her adeptness at female ejaculation in adult videos earned Akane the title, "Shiofuki Queen". She retired from AV work in 2008.

Hotaru Akane was born in Osaka, Japan on 25 October 1983. Akane's early appearances were under the stage name Anna Akizuki, and she debuted in AV using this name in an ensemble performance in the February 2004 adult video Faithful Dog 'Saseko', which won the award for Best AV Title at the 5th Takeshi Kitano Awards. By June 2004, she was appearing in solo videos such as Milky Sports for the Milky Prin studio. Later that year she was performing in featured actress videos for the major studios Wanz Factory and Moodyz. The November 2004 cosplay-themed Uniform Collection / Anna Akizuki had Akane donning a variety of school uniforms, a popular form of garment fetishism in Japanese AVs. In 2005, Weekly Playboy awarded Akane the "Newcomer of the Year" title in their "AV Academy Awards". and she also won a Best Actress Award for Excellence at the 2006 SOD Awards.

Kuki's January 2006 release, Cutie Clips, gave the viewer the experience of having a "virtual love story" with several top AV actresses. Akane's segment is a "virtual date" at the beach. Akane performed in the September 2006 ensemble work Dream School 10 from Moodyz which took 2nd Place in the 2006 AV Open competition. She also took part in another multiple actress video, Special Galactic All-Stars, from Real Works which won a Special Prize at the same contest.

Also in September 2006, Akane appeared in her first "uncensored" video, without the mosaic pixellation which is used to disguise the genitals in most Japanese porn films. She subsequently made four more original uncensored videos, all released by Sky High Entertainment.

Akane also had a role in director Toru Ichikawa's mainstream action film, Sekiryū no onna, which was released to theaters in October 2006.

For her ability to perform shiofuki or female ejaculation, Akane became known as the "Shiofuki Queen" of Japanese adult videos. Videos focusing on this talent include such titles as the December 2004 Hotaru Akane - Shiofuki Climax and Hotaru Akane - Paipan Mega Shiofuki Fuck from December 2007. Akane says that she prepares for her shiofuki demonstrations by drinking an entire bottle of water before performing in these scenes. In the June 2006 Hotaru Akane and Ayano Murasaki: Splash Heaven, the plot of the video has Akane competing with top jukujo or "mature" actress, Ayano Murasaki in this area of specialty in a contest to decide "Who is the best squirter in the AV industry". Love Splashing, released the following month, was a shiofuki-themed omnibus collection grouping Akane with such notable practitioners of the technique as Ai Kurosawa. In January 2007, Akane was chosen to be the actress in the inaugural entry of the new Ultimate Ecstasy series on the Real Works label.

She appeared in three Interracial videos in early 2007; Bring It On Denma Black Dude in January, Gal Dancer Black Dude Nakadashi in February, and Black Group Fuck in March with two other AV idols.
